Does IP helper forward subnet broadcasts?

Hi, I have a device on a VLAN that uses UDP subnet broadcasts to advertise its presence to similar devices.
This works fine on a single VLAN, but now I need to allow it to communicate with similar devices on a second VLAN.
I thought of using the IP helper command in the router, but I am wondering if that only forwards global broadcasts (255.255.255.255)?
My device sends out a subnet broadcast (e.g. 192.168.6.255)
Will IP helper change the destination address to the target subnet (e.g. 192.168.7.255)?

• It depends on the specifics of your setup but it could well help yes; have a look HERE to see if it helps.

  Eamon : I can't tell from that if it only sends global broadcasts or all broadcasts - am I missing something?

• got it working, but then hit a broadcast storm as described by Cisco here, http://www.cisco.com/en/US/docs/internetworking/case/studies/cs006.html Convinced customer to stick with one VLAN, so the problem as gone away.
  Thanks for the help
